OIL-BURNER.

v To all whom it may concern Be it known that I, IIARRY W. MANNING, a citizen of the United States, and 'aresident of Portland, county of Multnomah, State of Oregon, have invented a new and useful Improvementin Oil-Burners, of which the following is a specification. I r My invention relates to fuel oil burners intended for being installed in the fire-box of a stove or other heating apparatus;

The following are the particular features of my invention l 1. I provide my burnerwith a burnerhead which is adapted for being arranged to burn either with a circumferential flame, or

i with a vertical flame; the latterbeing de sirable when a cooking utensil is to be quickly heated by direct application of. the flame, instead of first having to heat up the entire stove. V I y 2. The gas generator of my burner is es pecially adapted for speeding up the gasifye ing ofthe fuel oil. To this end my generator preferably consists of a coil of horizontal pipes vertically stacked and 3. I provide an eflicient heating element for such generator, such element tending to distribute the flame along the entire length of-Ythe. generator so as to more efficiently" heat the latter. Y

The above features of my invention are illustrated in thetaccompanying drawings, the description of which, hereinafter; con-,

tained, fully discloses both the principles of construction and operation of my invention, invention also" includes incidental fea;

tures hereinafter fullydescribed. H v In said drawings Figure l is a top viewof my improved burner, the same being shown as provided with two burner-heads,

and the dome, or cover of one thereof is removed, as would be the case where the flame is to issue vertically from the burnerhead for direct application to the cooking utensil;

Fig. 2 is a side elevation of the same burner arranged in the same manner as illustrated in Fig. 2;

Fig. 3 is a section of the burner-head on the line 88 of Fig. 1, looking in the direction indicated by the arrow;

Fig. 4 is a larger-scaled section approximately taken on the line 414 of Fig. 2,

perspective secplate by which body of the gas generator 0. The latter consists of a coil of horizontal pipes vertically stacked. The generator is connected by a hollow Wire cl withthe tank (not shown) in whichthe supply of fuel-oil iscontained under pressure.

The heating element e of the generator consistsof a trough-like elongate body having channels as f on either side for containing asbestos to be saturated with alcohol for first starting the burner. The heating element 6 is alined with the coils of the generator a. The central longitudinal parts of the heating element is -arranged to form a gas chamber as shown in Fig. 4. I The bottom of this'gas chamber is closed by a plate gishown inFig. The top of the chambered portionv of the heating element is provided with'aplura'lity of transverse slits h as shown more clearly in Fig. 6, but that portion of said top directly opposite the pointof entrance ofthe gas mixture from theconduit a is left unslitted, and solid as at 6, thereby causing the flow of gas from the conduit to be divided, and to be uniformly distributingthroughout both "ends of said heatingelement. i

The conduit a is connected with the heater 0 by an elbow j as shown in Figs. 2 and 4'. The top of the elbow j is flat as at 7'", (see Figs. 4 and 7) and the bottom plate 9 of the heating element is provided with transverse slits 7a through which extend screw bolts Z. This arrangement is provided to permit the adjustment of the heating element so as to bring it properly in alinement with the generator c. The heating element is secured in place by bolts m.

The bottom of the air-and-gas mixing chamber 6 is controlled by a valve 12 adjustable by a rod 0 the valve being preferably so arranged as to admit some air at all times; in other words, so that it cannot be entirely closed, and thus always admitting some air.

The top of the mixing chamber 6 is closed by a cover 5.

p and 10 represent the burner-heads. They consist of a hollow body provided with a peripheral flange 9" on which is seated a ring 8 provided with horizontal circumferential slits t; and integral transverse bars u extend across the slitted portion, thus mak ing the ring a one piece construction.

On the open top of the hollow body of the burner-head is secured a slitted plate 0. This plate is preferably constructed as shown in Fig. 5. The plate is made with a perimetric perpendicular flange 'w, and the plate portion above said flange is provided with parallel slits w. I

The plate is also made with perforated ears through which extend the bolts .2. Across the bottom slitted portion of the plate '21, extends an integral bar 2, which serves topreVent the plate'from warping.

Over the slitted plate '0 there is supported on the burner-head, a dome 3.

When the dome 3 is in place, the gas will be compelled to issue through the slits t on the side of the burner-head. The burner is used in this way for heating up the stove. But when a cooking utensil is to be quickly heated by the direct application of the flame,

then the dome 3 is removed so that the gas may issue through the slits m of the plate a; and burn a vertical flame.

I claim: 7

1. 111 an oil burner of the type referred to, a burncr head comprising a hollow body provided with horizontal circumferentially extending slits, a plate fastened across the open top of the hollow bod such plate having aperimetric perpendicular flange, being provided with parallel slits above such flange, a dome or cap removably seated on the hollow body over said slitted plate, thereby compelling the gas to issue from said circumferential slits of the burnerbody.

2. In an oil burner of the type referred to, a burner-head comprising a hollow body provided with horizontal circumferentially extending slits, a plate fastened across the open top of the hollow body, such plate having a perimetric perpendicular flange, being provided with parallel slits above such flange, and having an integral reinforcing bar extending transversely to the slits along the bottom of the plate, centrally between opposite flanges thereof, a dome or cap removably seated on the hollow body over said slitted plate, thereby compelling the gas to issue from said circumferential slits of the burner-body. 1

3. In an oil burner of the type referred to, a burner head comprising a vertical hollow body, having an annular exterior chamber, open at the top, and inclosed by a circumferential slitted wall, a slitted plate closing the top of the hollow of said body, and a dome, or cap, removably seated on said wall, over said slitted plate and constituting a closure for the open top of said annular chamber, whereby when said cap is in place the gas is caused to issue from said circumferential slits in the wall of said annular chamber, and thus toproduce a circular flame, and when said cap is removed the gas is permitted to flow directly through said slits of the slitted plate, and thus produce'a vertical 4. In an oil burner of the type referred to, a burner head comprising a vertical hollow body, said hollow body provided with a peripheral flange, a ring seated on such flange, such ring constituting a Wall inclosing an annular space about said body, and having horizontal circumferentially extending-slits, a slitted plate closing the top of the hollow of said body, and a dome, or cap, removably seated on said ring, over said slitted plate and constituting a closure for the open top of said annular chamber,

whereby when said cap is in place the gas iscaused to issue from said circumferential slits in the wall of said annular chamber, and thus Xto produce a circular flame, and whensaid cap is removed the gas is permitted to flow directly through said slits of theslitted plate, and thus produce a vertical flame.
